Description
Pro-Ject Tube Box DS2 Phono Pre-amplifier
The Pro-Ject Tube Box DS2 Phono Pre-amplifier benefits from outstanding circuit technology from Dr. Sykora and uses high-quality components.
Compatible with both MM and MC cartridges. It offers connection for two turntables plus two selectable line outputs and a continuously variable selection of input impedance for low output MC cartridges while playing a record!
Other features include input capacitance for MM cartridges and switchable subsonic, that prevents your amplifier and speakers of ultra low rumble below 20Hz.
